Summary:	The remote host is missing an update for the 'squashfs' package(s) announced via the SUSE-SU-2023:4591-1 advisory.
Description:	Summary: The remote host is missing an update for the 'squashfs' package(s) announced via the SUSE-SU-2023:4591-1 advisory.

This is a regression introduced in August 2022, and it has been seen when tailend packing is used (-tailends option). * Fix build failure when the tools are being built without extended attribute (XATTRs) support. * Fix XATTR error message when an unrecognised prefix is found * Fix incorrect free of pointer when an unrecognised XATTR prefix is found. * Major improvements in extended attribute handling, pseudo file handling, and miscellaneous new options and improvements * Extended attribute handling improved in Mksquashfs and Sqfstar * New Pseudo file xattr definition to add extended attributes to files. * New xattrs-add Action to add extended attributes to files * Extended attribute handling improved in Unsquashfs * Other major improvements * Unsquashfs can now output Pseudo files to standard out. * Mksquashfs can now input Pseudo files from standard in. * Squashfs filesystems can now be converted (different block size compression etc) without unpacking to an intermediate filesystem or mounting, by piping the output of Unsquashfs to Mksquashfs. * Pseudo files are now supported by Sqfstar. * 'Non-anchored' excludes are now supported by Unsquashfs. update to 4.5.1 (bsc#1190531, CVE-2021-41072): * This release adds Manpages for Mksquashfs(1), Unsquashfs(1), Sqfstar(1) and Sqfscat(1). * The -help text output from the utilities has been improved and extended as well (but the Manpages are now more comprehensive). * CVE-2021-41072 which is a writing outside of destination exploit, has been fixed. * The number of hard-links in the filesystem is now also displayed by Mksquashfs in the output summary. * The number of hard-links written by Unsquashfs is now also displayed in the output summary. * Unsquashfs will now write to a pre-existing destination directory, rather than aborting. * Unsquashfs now allows '.' to used as the destination, to extract to the current directory. * The Unsquashfs progress bar now tracks empty files and hardlinks, in addition to data blocks. * -no-hardlinks option has been implemented for Sqfstar. * More sanity checking for 'corrupted' filesystems, including checks for multiply linked directories and directory loops. * Options that may cause filesystems to be unmountable have been moved into a new 'experts' category in the Mksquashfs help text (and Manpage). * Maximum cpiostyle filename ...
